I want to re-take some Chemistry AS and A2 modules that I first took in 2014 and 2015 (Years 12 and 13), in the summer of 2017. I am aware, however, that there is a new specification coming in for the A-Level reforms. Would I be able to take re-sits for the 2014 and 2015 specification in the summer of 2017 or would it be too late to do so at that point?

You should be able to re-sit A2 units but I'm not sure about AS. The provisional timetables for next summer should have been published so you could check.
